Children made nest boxes and learned how to provide homes for birds in their gardens.
The event at Rutland Water was part of British Trust for Ornithology’s National Nestbox Week.
It aims to increase nesting places for birds, bugs and bats as natural sites such as holes in trees or old buildings have been disappearing.
Rutland Water’s education officer Joelle Bryan said: “The children made nest boxes for robins, blue tits, bugs and bats and bird feeders.
“We showed them how to look after it by cleaning and changing the nest every year. They seemed to have a lovely time.”
The 17 children who attended were also shown how to hide materials such as hair from brushes, pet hair and lint from tumble dryers in the garden for the birds to find and make new nests.
